Swing MVC模型

我尝试使用Swing创建一个MVC应用程序。但是，我对实现方式和事物应该如何处理感到困惑。我的意思是：

I have the Gui which is the view all the logic send to a class named controller and I have a model where I have model properties.(I have read MVC is like that)
I create some Random codes in view with input of how many codes I want and transfer this with ActionListener to a Class Named Controller. The Random codes generated with a button on the controller class in a method . The random codes are generated and then i want to save them on a database. I am confused how to save the generated codes on the database. Should i create a method in the Class Named Controller so that i can save them from there? Or another different class with save update find.......... methods? If Yes then why I have create the Model class with Model properties? And how can I use the Model class. what is only left to understand how to use the Model class if I have to use it or if I just have to have this class so that is there. What is the use of Model class if it's only to be there with the properties and do save some where else? What approach is usually used so that I am ok with MVC pattern? Am I confused? Any help I forget to tell that I use Hibernate. thanks ps. I have also read this http://java.sun.com/products/jfc/tsc/articles/architecture/ but i didn't understand it.
```
public class code(){// this is the Model
    private int i;
    public void setter(int i){
        this.i=i;
    }

    public int getter(){
        return i;
    }

    public String generateStringInt() {
        return new BigInteger(190, random).toString(32);
    }

    // what ever i want to create with the int i variable i will do it on this class?
    ///then i will pass it on the controller to sent it on the view  
    //OR save if i want to save it.?Is this way of thinking right?
    //Or is there any other way to do it ?
    /// if i have a Button and press it from the View it will generate this method?or
    // i have to do it else?
    public String generateStringInt() {
        return new BigInteger(190, random).toString(32);
    }

 }

 //then if i want to save i can just do it like 
 //session.save(object) or is there any other way?
```

现在好了吗？谢谢

让我为您解释一下... Model - 业务逻辑和数据 View - 模型输出的展示 Controller - 处理操作的地方。

Java中的Swing基于MVC，也被称为PLAF（可插入外观）。

使用这种MVC体系结构的优点是，可以保持相同的模型并不断更改视图。

例如:

拥有一个运行计算器程序的模型。

现在将此模型并使用Swing或JSP反映输出，一个用于桌面，另一个用于Web。

在Swing应用程序中，MVC序列顺序如下...

Action is done on the Controller
Controller tells the Model about it
Model make necessary changes, according to the Action
Controller informs the change in state of Model to the View
View will update itself.

在Web应用程序中，MVC的顺序如下...

Action is done on the Controller
Controller tells the Model about it
Model make necessary changes, according to the Action
Now Controller informs View and Also make the Changes reflect in View
